Insect defoliation modulates influence of climate on the growth of tree species in the boreal mixed forests of eastern Canada. [PDF]

open access: yesEcol Evol, 2022
Positive effects of a warmer climate on tree growth may be offset by insect outbreaks. Non‐host trees are most likely to benefit from climate warming. Impact of the insect outbreaks extends over most of the trees’ lifespan. Abstract Increasing air temperatures and changing precipitation patterns due to climate change can affect tree growth in boreal ...

Trophic niche partitioning between two prey and their incidental predators revealed various threats for an endangered species. [PDF]

open access: yesEcol Evol, 2022
We have reconstructed the trophic niches of two ungulate prey, moose and Atlantic‐Gaspésie caribou, and of two incidental predators, coyote and black bear, living in sympatry in a protected area surrounded by intensively disturbed habitats. Using stable isotopes, we showed a small overlap in dietary niche for the two sympatric ungulates, suggesting a ...

Dynamiques hydrogéomorphologiques historiques et actuelles d'une rivière perturbée par les activités de la drave et analyse des impacts d'un démantèlement de barrage

open access: yesCanadian Geographer / Le géographe canadien, Volume 67, Issue 4, Page 537-549, Winter / hiver 2023., 2023
Résumé Au Québec, la dynamique fluviale de la rivière des Escoumins a été perturbée par l'industrie forestière pendant plus d'un siècle. Un barrage a notamment été construit près de l'embouchure en 1846, puis démantelé en 2013. Ces perturbations ont entraîné des répercussions importantes sur l'équilibre du cours d'eau et sur l'habitat du saumon ...

Competition and site weakly explain tree growth variability in undisturbed Central African moist forests

open access: yesJournal of Ecology, Volume 111, Issue 9, Page 1950-1967, September 2023., 2023
This study quantified the effect of factors influencing tree growth in Central African forests using data from a network of large permanent plots. At the population level, the best growth models were highly variable for the 43 species studied, with tree diameter emerging as the strongest predictor of tree growth.

PhenoCaB: a new phenological model based on carbon balance in boreal conifers

open access: yesNew Phytologist, Volume 239, Issue 2, Page 592-605, July 2023., 2023
Summary Traditional phenological models use chilling and thermal forcing (temperature sum or degree‐days) to predict budbreak. Because of the heightening impact of climate and other related biotic or abiotic stressors, a model with greater biological support is needed to better predict budbreak.

Close-to-nature silviculture in eastern Quebec: Advances over the last decade

open access: yesThe Forestry Chronicle, 2021
The increase in intensity of the harvesting of eastern Quebec’s forests has resulted in profound compositional changes at the stand level. The composition and structure of presettlement stands provide key benchmarks when implementing ecosystem-based ...

Tree-Related Microhabitats Are Promising Yet Underused Tools for Biodiversity and Nature Conservation: A Systematic Review for International Perspectives

open access: yesFrontiers in Forests and Global Change, 2022
Sustainable management of forest ecosystems requires the use of reliable and easy to implement biodiversity and naturalness indicators. Tree-related microhabitats (TreMs) can fulfill these roles as they harbor specialized species that directly or ...
